[0022] like Figure 1-5 This utility model discloses a ventilation device for a high-temperature purification furnace, including a high-temperature purification furnace 1. A fixed shell 2 is provided on the top wall of the high-temperature purification furnace 1. A sealing component 3 is provided on the top wall of the high-temperature purification furnace 1 and located on both sides of the fixed shell 2. A branch pipe 4 is inserted into the sealing component 3. A ventilation pipe 5 is connected to the branch pipe 4. A fastening device 6 is provided in the fixed shell 2. A tray 7 is connected to the upper part of the fastening device 6. A clamping device 8 is provided in the tray 7 and can fix the ventilation pipe 5.

[0023] like Figure 1 and 3 The fastening device 6 includes a wire drum 9 with a lever 19 for turning. The lever 19 facilitates the turning and rotation of the wire drum 9. The wire drum 9 is rotatably fastened in the fixed housing 2. A screw 10 is threaded into the wire drum 9. The upper end of the screw 10 is fixedly connected to the bottom of the tray 7. The bottom of the tray 7 is provided with a guide rod 11 and a baffle 20 at the lower end of the guide rod 11. The baffle 20 prevents the guide rod 11 from detaching from the fixed housing 2. The guide rod 11 is inserted into the fixed housing 2. By turning the wire drum 9, the screw 10 will pull the tray 7 downward, thereby tightly sealing the branch pipe 4 into the sealing assembly 3, completing the rapid installation and sealing of the high-temperature purification furnace 1.

[0024] like Figure 1 and 4 The sealing assembly 3 includes a sealing sleeve 12. The sealing sleeve 12 has an exhaust channel 13 inside, and its diameter is smaller than that of the branch pipe 4. The sealing sleeve 12 has a sealing gasket 14 inside, and the diameter of the sealing gasket 14 is equal to that of the branch pipe 4. The branch pipe 4 is pressed against the sealing gasket 14, which can exhaust and seal the branch pipe 4.

[0025] like Figure 1 and2 The clamping device 8 includes a clamping plate 15, and an anti-slip pad 18 is provided on the inner wall of the clamping plate 15. The anti-slip pad 18 is made of rubber.

The mating plate 16 can be tightly fixed through the threaded hole 17, so that the clamping plate 15 can complete the tight fixation of the ventilation pipe 5.

[0026] In practical use, when installing the ventilation pipe 5, first place the ventilation pipe 5 in the clamping plate 15, then fasten the clamping plate 15 so that the connecting plate 16 is connected together. The ventilation pipe 5 can be clamped and fixed by screwing the bolts into the threaded hole 17.

[0027] Then, insert the branch pipe 4 into the sealing sleeve 12, rotate the screw drum 9, and the screw rod 10 will be threaded into the screw drum 9. The guide rod 11 will slide in the fixed shell 2. The screw rod 10 will pull the tray 7, and the tray 7 will pull the ventilation pipe 5 down as a whole. As a result, the branch pipe 4 will slide into the sealing sleeve 12 until it is pressed against the sealing gasket 14. The sealing gasket 14 can seal the branch pipe 4 to prevent air leakage, thus completing the sealing and fixing of the ventilation pipe 5 and the branch pipe 4.

[0028] During disassembly, simply turn the screw spool 9 in the opposite direction, and the screw rod 10 will push the tray 7, causing the clamping device 8 to move the ventilation pipe 5 upward as a whole, so that the branch pipe 4 can be pulled out from the sealing sleeve 12 for cleaning, which is very convenient.
